Question

TEST FOR CONVERGENCE OR DIVERGENCE THE SUMMATION OF Un=(7r)to the power r .from r=1 and infinity

Answer 1

Do you mean\[U(n)=\sum_{r =1}^{n}(7r)^{r}\]

Answer 2

exactly the one above

Answer 3

OK so do you know what to do next? Do you know the type of series is represented?

Answer 4

no

Answer 5

Answer 6

It reads "The sum of seven r raised to the rth power from r equals one to infinity". Right?

Answer 7

\[\sum_{r =1}^{n}(7r)^{r}=\sum_{r =1}^{n}7^{r}r ^{r}\]Agreed or disagreed?
